  • Patent number: 3983981
    Abstract: A viscous fluid clutch wherein a fluid medium functions in response to ambient temperature changes to transmit torque between relatively rotatable input and output members by variably filling a predetermined shear space therebetween with a viscous fluid medium, the shear space consisting of interdigitated concentric annular grooves formed on adjacent faces of the input and output members, each groove being approximately 0.060 inch wide and 0.270 inch deep, with the lands separating adjacent grooves being approximately 0.040 inch wide, and the fluid medium used in conjunction therewith having a viscosity of approximately 3,000 centistokes, the combination producing improved results with respect to inhibiting boiling of the radiator coolant and prolonging fluid medium operational life.

  • Patent number: 3961504
    Abstract: An automotive trunk lid latch assembly including a housing, a pair of latching members and a cam member, each rotatably mounted in the housing, a shaft extending into the housing from a lock cylinder assembly and adapted to rotate the cam member in response to manual rotation of a key in the lock cylinder assembly, and a spring-loaded lever rotatably mounted intermediate the cam member and one of the latching members and retained therebetween by the end of the shaft, and adapted to be rotated by the cam member to, in turn, unlatch the latching members. In the event of removal of the shaft, the spring-loaded lever will snap away from the cam member into an inoperable position, thus preventing any unlatching operation thereafter by the insertion of a probe or a screwdriver to rotate the cam member.

  • Patent number: 3940580
    Abstract: The control mechanism described herein includes an instrument panel-mounted shift control knob assembly which serves to selectively rotate a pulley and belt arrangement to thereby move a pivotally mounted bellcrank lever connected to the belt and to which a transmission shift control cable is operatively attached. Associated with the control knob assembly and with an adjacent lock mechanism is a series of linkage members which serve to concurrently lock the steering wheel and the parking brake in response to the positioning of an ignition key in the "Lock" position in the lock mechanism only after the control knob is manually placed in the "Park" position and the parking brake is manually applied. Additionally, a starter switch is associated with the control mechanism whereby the switch may be operated only in the Park or Neutral positions.

  • Patent number: 3937104
    Abstract: An automatic transmission power train including an improved torque-pressure transducer incorporating dual concentric outer turbine and inner transducer shafts, secured together at their input ends, and having a regulating valve mounted in the center of their output ends, with the axial movement of the regulating valve being controlled by a plurality of spring-loaded, axially aligned cam members, each having oppositely disposed tabs formed thereon for alternately extending through one set or both sets of oppositely disposed relatively movable longitudinal slots formed in the two shafts, with the spread of the cam members being changed by camming action in response to the relative twists of the concentric shafts, and the regulated transducer pressure thus produced being directed to a modulator valve assembly for transmittal to the conventional transmission shift valves.
